'1 Claims; (01. 5-472) The main objects of this invention are:

First, to provide an improved wall bed having a supporting mechanism associated, therewith for allowing the bed to be moved through an opening considerably narrower than the bed. a

Second, to providers mechanism of this character in which the bed is centrally supported so V that it is balanced on its supports.

Third, to provide a mechanism. of this type which is simple and compact yet strong and rugged and which, while connected. to a support at only two points, carries the bed at its center throughout the entire cycle of operation of the device.

Objects relating to details and economies of my invention will appear from the dcscriptionto follow. The invention is defined and pointed .out-

a line corresponding to line 2-2 of Fig. 6, the.

dotted lines indicating the various positions of the bed as it is moved throughthe door opening;

Fig. 3 is an enlarged fragmentary perspective view of the lower end of the supporting mechanism moved'to about onefourth open position.

Fig. 4' is a similar view showing the relation of the parts withthe bed in approximately half open position. 7 1

Fig. 5 is a similar view showing. the relation of the parts in full open position,

. Fig. 6 is a fragmentary view sectioned mainly through the base of thes'upporting mechanism,

and 1 Fig. 7 is a fragmentary perspective view of a modified form of the lower supporting mochanism.

, Referring to the drawings, numeral 1 indicates a wall having a door opening-2 leading to a closet 3. The opening 2 is'pr'ovided with a door frame 4. for the conventional door 5. The

frame 6 of the wallbed '7 is provided with upper and lower frame supporting brackets 8 and 9 which have downwardlyfacing socket bearings 10 coacting withthe upwardly projecting pins 11 on the outer ends of the supporting arms 12 and 13. These supporting arms have downwardly projecting bearing pins 14 which engage the up & WireCorporatimu,

ported, the arms swing about their'pivots and thebed frame is pivot-ally mounted on the arms.

The bed frame brackets are secured to the bed frames so that the pivots of the bed frame on the arms are centrally of the frame which bal-- ances theframe and avoids thenecessity of legs at one side of the attached end of the bed frame as is common practice in structures of this charactor in which the frame pivots are commonly at one side of the centerin order to enable the frame to be moved through a door opening.

The movement of the bed frame on its pivots on the arms is controlled by a mechanism comprising the lever 19 which is pivotally connected at its inner end to the lower arm 13 adjacent its inner end, the lever being mounted on the pivot 20. and disposed on the underside of the arm 13so that the arm may swing overit. The leveris provided with a follower roller 22'carried bythestub shaft 21, a ball'bearing being preferably provided for this follower roller.

Theouter end of; they lever 19 is connected to the bed frame by means of the'linl: 25, the link being pivoted at 24 to the lever and at 26 to the bed frame. 7 q

The floorplate 1'7 isprovide' d with a flange. like cam 27 having a straight portion 28' at inner end,a flange 28' being arranged lIl-Spi(3d relation to this straight portion of the flange to provide a throat adapted to receive the cam followerwhenthe bed is in its-completely collapsed position, this serving to prevent oscillating move ment of the bed on its pivots on the arm; that is, holding it in that collapsed positionuntilthe bed is manuallymanipulated to swing it through the door opening,

This arrangement gives a compound movement to the bed; that is, the movement resulting from the swinging of the supporting arms the movement resulting-from the pivoting of the on the arms, this movement being such that the;

outwardly I PEER,"-

bed can be' sw'ung through a relatively small,

opening and permitting the connection of the bed at a central point. The lever 19 has an offset at its in er end which permits its pivotal connection to the arm to to-substantiallyjopposite sides for the pivot for the arm see the dotted line position inllig. 2.

In operation, the guide means permits tzie bed" to be swung first through an'arc ofabout 80 about the pivots at thofouter a? the upper and lower arms. The dotted lines 29' of Fig. 2

illustrate the bed in this position. The frame is then swung about the pivots at the inner ends of the arms through an arc of about 35 to the position illustrated by the dotted lines Finally', the bed is swung about theinner and outer vertical axes to the fully opened position illus trated by the dotted lines 31. The entire move ment of the'bed in passing through the door opening 2 is controlled by the guiding means. In this movement, the bed is supported at all times at its center and freely passes through the door opening. By reference to Fig. 2, it will be observed that when the bed is in the closet 3 and when the bed is in the room, there is sufficient room between the bed'and the door frame to permit a person to enter and leave the'closet 3 without disturbing the'bed. r V

In the modificationillustrated in Fig. 7, the

socket member 15' of the floor 'plate 17 is pro.

vided with an upstanding plate-like bracket 16 which is secured to the door frame. This structure provides a stronger lower supporting mechanism, the lower arm 13 being'pivoted to the socket member 15'. a

It will be appreciated that I provide a control mechanism which is supported at two points only and which supports and controls the movement of the bed through the door opening. With my improved apparatus, .a 4x4 bed may be-conveniently passed through a door opening only 2' 8" Wide, leaving room for accessto the closet. Furthermore, the support is provided with a single materially strengthen the mechanism. Further, the device is simple and compact in construction, economical to manufacture, I extremely efiicient in operation, and obviates the use of castors.-

, It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiments of my invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

Having thus described my invention, what I claim as new anddesire to secure by Letters Patent, is:

l. A wallbed comprising a bed frame, a door frame, brackets on said frames, upper and lower arms pivoted to said bed frame and said door frame brackets, and means including a cam and cam follower connected to said frames for controlling the movement of said bed frame, whereby it pivots about the inner and outer ends of said to pass through the door frame. 2.
